Key Features and Technical Specifications
The Rosemount 3051SFA Annubar Flow Meter combines the industry-leading 3051S SuperModule™ platform with the patented Annubar™ averaging pitot tube technology. This synergy creates a "no-equal" solution for liquid, gas, and steam applications.
- Energy Efficiency: The patented T-shaped Annubar sensor creates a fixed separation point for improved DP signal stability while maintaining a small profile in the pipe. This design reduces permanent pressure loss significantly compared to traditional orifice plates, leading to substantial energy savings.
- Multivariable Precision: The system integrates pressure, temperature, and flow measurements into a single device. By utilizing the emerson 3051sfa transmitter capabilities, it provides fully compensated mass and energy flow data, eliminating the need for multiple pipe penetrations and separate instruments.
- High Performance: Offers "Ultra for Flow" performance with up to ±0.04% accuracy and a wide 14:1 flow turndown, ensuring reliable data even in changing process conditions.
- Easy Installation: As a fully integrated flowmeter, it reduces potential leak points and simplifies installation by eliminating impulse lines and extra fittings.
